Steel Fiber: Max for maximum armor amount.
Vitality: Max for maximum health amount.
Quick Rest: Max for stamina recharge.
Rage: Center of the build - Take health damage to recharge energy.
Continuity: Maximize to extend your hysteria ability.
Steamline: Maximize to make hysteria easier to cast in the face of energy drains.
Narrow Minded: As max as possible to extend hysteria, while minimizing the 7% per mob hit at the end of ability.
Constitution: Extends hysteria, and helps keep you on your feet to recast as needed.
This build will keep you in a constant hysteria. It can solo Corrupted Vor without a problem. Be careful of corpus neutralizers, as they are meant to be Valkyr killers. Target them above anything else, kill them FAST, and recast hysteria ASAP after taking them out. Carry energy restores for those just in case moments, when hitpoints are low, and you have no energy.
For your kubrow, ensure you have Pack Leader, Link Armor, and Link Health equipped and as maxed as you can get them. Since your valkyr is nearly 100% melee, the kubrow should be just as unstoppable as the Valkyr.
